I am trying to work out how to store approximately 1000 lines of text (3 columns, 
30 chars each) inside an application. I want to read the values and then display 
them in a TStringGrid and do some further manipulation.

Answer:

If you want to read the data into a stringgrid a way to do that without building a 
class around the resource data would be this. You start by placing the data into a 
file and the file into a resource as detailed in Tip Number 1004. Loading this data 
into a TStringGrid would work like this:


1   procedure LoadResourceIntoGrid(grid: TStringGrid);
2   var
3     rs: TResourceStream;
4     numElements: Integer;
5     datarec: TFileData;
6     i: Integer;
7   begin
8     rs := TResourceStream.Create(hInstance, 'FILEDATA', RT_RCDATA);
9     try
10      numElements := rs.Size div Sizeof(numElements);
11      grid.Perform(WM_SETREDRAW, 0, 0);
12      try
13        grid.RowCount := numElements + 1; {assuming a header row}
14        {following assumes grids colcount has been set correctly already}
15        for i := 1 to numElements do
16        begin
17          rs.ReadBuffer(datarec, sizeof(datarec));
18          grid.Cells[grid.FixedCols, i] := datarec.col1;
19          grid.Cells[grid.FixedCols + 1, i] := datarec.col2;
20          grid.Cells[grid.FixedCols + 2, i] := datarec.col3;
21        end;
22      finally
23        grid.Perform(WM_SETREDRAW, 1, 0);
24        grid.Invalidate;
25      end;
26    finally
27      rs.free
28    end;
29  end;
